Oil of clove
Clove oil is a natural analgesic and antiseptic, used primarily in dentistry for its main ingredient eugenol. It can also be purchased in pharmacies over the counter as a home remedy for dental pain relief, mainly toothache. It is also often found in the aromatherapy section of health food stores, and is used in the flavoring of some medicines. Madagascar and Indonesia are the main producers of clove oil.
There are three types of clove oil:
- Bud oil is derived from the flower-buds of S. aromaticum. It consists of 60–90% eugenol, eugenyl acetate, caryophyllene and other minor constituents.
- Leaf oil is derived from the leaves of S. aromaticum. It consists of 82–88% eugenol with little or no eugenyl acetate, and minor constituents.
- Stem oil is derived from the twigs of S. aromaticum. It consists of 90–95% eugenol, with other minor constituents.
Particularly in South Korea and India, eugenol, a phytochemical extracted from clove oil, is used to relieve toothache. Applied to a cavity in a decayed or extracted tooth, eugenol or clove oil can relieve toothache temporarily. The potential mechanisms for how eugenol may inhibit dental pain are under active research.
Use on fish
Taking cloves or clove oil in large amounts may cause nausea, vomiting, abdominal pain, diarrhea, burns in the mouth and throat, sore throat, seizures, difficulty breathing, rapid heartbeat, sleepiness, intestinal bleeding, and liver or kidney failure. More serious effects have been reported in young children, even with small doses.

Clove oil and eugenol, one of the chemicals it contains, have long been used topically for toothache, but the FDA has reclassified eugenol, downgrading its effectiveness rating. The FDA now believes there isn't enough evidence to rate eugenol as effective for toothache pain.

Both clove and benzocaine gels had significantly lower mean pain scores than placebos. No significant difference was observed between clove and benzocaine regarding pain scores.
